The High Velocity Oxy Fuel (HVOF) spray method is commonly used to deposited carbide-based cermet- is a class of wear resistant material that has been extensively investigated and has versatile industry applications due its advantageous combination of hardness, toughness and wear properties.

In this work we present single layer carbide-based coatings that can have potential applications in erosive-corrosive environment and also candidates for hard chrome plating replacement. Furthermore, coatings produced in this study exhibited low porosity, high hardness and can be super finished to Ra= 0.1 µm or better, which are general requirements especially for a hydraulic component
